wnnnnnn DEVICE This invention relates to a wheeled device,

and has for an object to provide an improved wheeled device suitableforvehicles of vari ous nature.

Q 7 A further object of this invention is to providean improved, wheeleddevice, which may have a 'sprin mechanism forv the vehiclecombined witthe wheeled device.

Still a fin therobject of this invention is 5% toprovidea wheeleddevicewhichcan travel overa very rough surface and still .be able to travelthereover without transmitting any violent shock of the vehiclesupported by the heel d vice. a

Still a further object of this invention is to provide a wheeled devicewhich will en able the vehicle supported thereby to climb or descendcurb, stones, or'similar obstructions with great facility.

provide an improved Wheeled device which isespeciall suitable forbabycarriages, enablingthe baby carriage to be takenup and down a curb stonewith great ease, enabling 3 it to mount or dismount on a curb stoneeasily withoutthe necessity of the operator having totilt the vehicle toget it over the curb st n 7 Yet a further object of this invention is toprovide an improved wheeled device which maybe used for other vehiclesas well, such as aeroplanes, wheelbarrows, or any other type, of vehicleto which itmay be applied,

Yet a further object-of this invention is to. provide, an improvedwheeled device consisting of a wheel operating on a main axle and.havinga plurality of small wheels aflixedton' the periphery of themainwheel, there being three, four or more small wheels individually affixedon the main wheel at several spacedpointsthereabout. t v a Stillanotherobject oftthis'invention is to provide a spring mounting andsupport for the axle of the main wheel, which: spring mounting may ormaynot take theplace-of the usualspring provided on the vehicle;

With the "foregoing andother objects, in view, as, will; hereinafterbecome apparent, this, invention comprises the' v constructions,

combinations, and arrangements of. parts,

hereinafter set forth, disclosed and shown on the accompanyingdrawing. IIn this draw- 1110., v Figure l is a front elevation of-the wheel, 1

the wheel 11 consisting of two platemembers- V 13, having a pluralityofsmall wheels, in this case 1, mounted between the plates 13, thewheels 14 each being individually sup-; ported on individual axles 15connecting the 13 are each recessed between the axles'l5 as shOWn, at16, so as to enable it to clear any obstructions, as. clearly shown inFigures 4 and 6.

parallel to'each other'and secured together by a bridging member 25, theaxle, portions 12 and 19,,passing through each or these platemember's'23 and 24. A slot 26 concentric withtheaxle lgreceives theaxle-portion 12. r

The axle portion 1 2 is secured by a spring member 27 to "another'bridgemember 28'v se -f curing the support portions 23 and 24 to-'1 gether.The spring 27 normally holds the cesspressure exerted downwardly by thevehicle on the support 22 ,1i't allows the'support22$to swingdownwardly'with theaxle 1 9 5 plates 13 of the main wheel-11. Theplates; f

As previously set forth, the vehicle may be of any suitable nature,thus, in Figure 4,

there is shown one form of vehicle towhich this Wheeled device 10 hasbeensec'ured, this vehicle comprising a baby carriage 30 having theusual handle 31. In operation. the baby carriage 30 is pushed alongbythehandle 31 in the usual manner supported on any two individual wheels 14of each Wheel device 11, there being obviously four wheel devices 11secured thereto by means of the support 22 extendingfrom each corner ofthis baby car riage' 30. .l/Vhen an obstruction is reached, such as acurbstone shown at 32, the particular wheels 14 striking the curbstonewill stop and the wheel device 11 will rotate about t e axle 12 as awhole enabling the next individual wheel 14 to pivot'ontothe top of thecurbstone. Then the wheel 14 that struck the curbstone will merely riseup on top of the curbstone. In'the sameway the rear wheels will mountthe curbstone. This saves the operator of the baby "carriage from thenecessityof having to tilt the carriage as it will'autom'atically mountand in. a similar manner automatically dismount from" the curbstone withthe least amount of shock to the baby in the carriage and with theileastamount'of tilting of the carriage.

In Figure 5 the same type of heeled de-v vice is shown as applied-to anaeroplane 33,

the wheel device in this form acting as a landing carriage. When theaeroplane lands and an obstruction is struck as it rolls along, thewheel, instead of nosing over as the ordinary aeroplane would, the wheeldevice 11 merely rotates about its axle 12 and climbs over theobstruction. y

In Figure 6 a wheelbarrow has been shown as making useof this wheeleddevice, the wheelbarrow 34 having a wheel device 11 secured thereto attheaxle 12. The usual difficulty of'causing a wheelbarrow to mount up ordown a-curbstone is too well known to need further'discussion. With thisinven tion, however, when a-curbstone' is struck,

shown and the structure described in'detail,

it is obvious that this is not to be limited to the exact form disclosedexcept as claimed and that changes may be made therein within the scopeof what is claimed, without departing from the spirit of the invention.

Having thus set forth and disclosed the nature of this invention, whatis claimed is:
